LEWIS B. POST, OF BRADFORD, PENNSYLVANIA, ASSIGNOR OF ONE-HALF -TODOMINIO GUIDO, OF BRADFORD, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. '762,7 58, dated June14, 1904. `Application filed October 24, 1903. Serial No. 178,444.(Nolmodel.)

To all whom, t may con/cern.:

Be it known that I, Lewis B. Postr, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented new an d useful Improvements in Pipe-Couplings, of whichthe following is a specification.

My invention relates to improvements in pipe-couplings, andpertains'more particularly to that class of detachable couplings.

rI he object of my' invention is to provide a detachable pipe-couplingwhich is more simple, cheap, and durable than any heretofore poluced andwhich is also more easily coup e In the accompanying drawings, Figure lis a vertical sectional view of my coupling, showing the pipes inposition and locked therein. Fig. 2 is an end view of my detachableclamping member. Fig. 3 is a side elevation of one of theclamping-bolts. Fig. 4 is an end view of one of my wedges. Fig. 5 is anenlarged sectional view of one of the wedges,

showing the packing in position before it is compressed. v

Referring now to the drawings, A` represents cylinder or sleeve, whichis of a size considerably larger than the diameter of the pipe. The saidpipes are represented by Band O, which are adapted to enter saidcylinder or sleeve A, and their inner ends extend adjacent the centerthereof.

Surrounding each pipe B and O within the cylinder or sleeve A are twowedges D and E. The said wedges, as shown in Fig. 4, are

of a circular form and surround the pipes B and O. The said wedgesbeingY arranged on each pipe so that one will pass over the other, theyare thus adapted to bel wedged together and make a tight joint betweenthe pipe and sleeve, thus preventing the leaking of liquid or airtherefrom, for whichever the said pipes are adapted to be used. Theouterface of the wedge D is provided adjacent the end CZ with an annularrecess D', which is adapted to receive the round gasket F, and the innerface of said wedge D, opposite the recess D', is provided with aninwardly-extending annular beadingD2, which forms a space between it andthe opposite or otherV circular wedge 5o E. The outer face of said wedgeE, adjacent its` rear end e, is provided withV an annular gasket-recessE/, which is adapted to receive the gasket G, and the inner face of saidwedge E, opposite the recess E', is provided with an 55 annular beadingor ledge E2, and thus it will be seen that the two wedges are simplyplaced upon the pipe with their ends extending in oppositev directions,the outer wedge D passing over the inner wedge D. Fitting between the 6otwo lwedges is apacking H, which is of a form 'like that shown carriedby the two wedges.

'While I have here shown the wedges provided with the flange or beadingD2 and O2, I do not care to limit myself to the same, as the operationwouldbe the same if I simply used the annular gasket-recess between thetwo wedges. It will be readily seen that by pressing or forcing theouter wedge D inwardly the smooth surface of the sleeve engages thegasket D 7o and compresses the same, while the same is being done withthe gaskets E and H, and after the same has been forced inward, as shownin Fig. 1, the same will retain said position and firmly hold thepipesfwithin the sleeve. In order to morel evenly press or force thesaid wedges D inwardly than can be done by hand or has been done byother de- Vices,I provide a ring I, which is made in two sections andhinged together at z' and is 8O adapted tov fit around the sleeve A, andby making the same in two sections and bringing them together it is seenthat the same can be readily removed and used in connecting up the pipesat different points along the v line of' pipes. The ends of the twosections of which said ring I is made opposite the .pivotal point/arebolted together and adapted to be drawn tightly together and clampedupon the sleeve at any desired point. The said ring is provided with anynumber of outwardly-extending ears J, which are .provided withscrew-threaded openings j', into which are adapted to screw the bolts K.The said v bolts have the squared ends K', provided with 9 5 openings r,adapted to receive an instrument for turning the same, and thus thebolts are moved Within said openings. The opposite end of said boltshave a reduced rounded end L, which has, its extreme outer endscrewthreaded. Loosely itting on said reduced portion of the bolts arethe L-shaped members M and screwed upon the outer end of said reducedportion are the nuts N, which hold the member M thereon, yet allow thebolt to rotate within the same. The inwardly turned end m of theL-shaped members M pass within the space between the pipe and the sleeveand engage the outer ends of the wedges D, and by means of the saidbolts K the wedges are forced inwardly and the pipe is coupled together,and the device may be removed from the sleeve to be used on anothercoupling.

Having thus described my invention, what I claim as new, and desire tosecure by .Letters Patent, is-

l. A pipe-couplingcomprising a sleeve adapted to receive the ends of thepipe, wedges within said sleeve, and circular gaskets adapted to beexpanded between said wedges.

Q. A pipe coupling comprising a sleeve adapted to receive the ends ofthe pipe, circular wedges surrounding the pipes within the sleeve andgaskets adapted to be expanded between said wedges.

3. A pipe coupling, comprising a sleeve adapted to receive the ends ofthe pipe, circular wedges surrounding the pipe within the sleeve, agasket between said wedges, and a second gasket' between the outer wedgeand said sleeve.

4. A pipe coupling, comprising a sleeve adapted to receive the ends ofthe pipe, circular wedges surrounding the pipe within the sleeve, agasket between the wedges, a second gasket between the outer wedge andthe sleeve, and a third gasket between the inner wedge and the pipe.

5. A pipe coupling comprising a sleeve adapted to receive the ends ofthe pipe, circular wedges surrounding the pipes and overlapping eachother, gaskets between said wedges and between said outer wedge and thesleeve and the inner wedge and the pipe.

6. A pipe coupling comprising a sleeve adapted to receive theends of thepipe, circular wedges surrounding the pipes and one wedge overlappingthe other and extending in opposite directions, gaskets between saidwedges and between the outer Wedge and the sleeve and the inner wedgeand the pipe.

7. A pipe coupling comprising a sleeve adapted to receive the ends ofthe pipes, circular wedges surrounding the pipes Within the sleeve andone wedge overlapping the other and extending in opposite directions,gaskets between said wedges and between the outer Wedge and the sleeveand the inner wedge and the pipe, and means for forcing the outer wedgeinwardly.

8. A pipe-coupling comprising a sleeve adapted to receive the ends ofthe pipe, wedges surrounding said pipe within the sleeve, a circularmember adapted to be clamped to said sleeve, and having screw-threadedopenings therein, bolts adapted `to be screwed within said openings, andL-shaped members swiveled to the outer end of said bolts and adapted toenter the space between thepipe and the sleeve and engage said wedges.

9. A pipe coupling comprising a sleeve adapted to receive the ends ofthe pipes, wedges between said pipes and sleeve, and having depressionstherein forming ribs on the opposite sides, and gaskets within saiddepressions.

10. A pipe-coupling comprising a sleeve adapted to receive the ends ofthe pipes, Wedges between said pipes and sleeve and overlapping eachother, and said outer wedge having an inwardly-pressed depressionforming a rib on the inside and the inner wedge having an outwarddepression forming a rib on the outside. l1. A pipe-coupling comprisinga sleeve adapted to receive the ends of the pipe, circular wedgesextending in opposite directions and overlapping each other and havinggasketreceiving recesses in their inner and outer faces and gasketsadapted to be compressed within said recesses.

12. A pipecoupling comprising a sleeve adapted to receive the ends ofthe pipes, circular wedges surrounding the pipes and extending inopposite directions and overlapping each other, and havinggasket-receiving recesses in their inner and outer faces, gasketsadapted to t within said recesses, a detachable ring carried by saidsleeve and having screwthreaded openings therein, bolts screwed withinsaid openings, L-shaped members swiveled on the ends of said bolts andadapted to enter the space between the pipes and the sleeve to engagethe outer wedge and force the same inward.

13. A pipe-coupling, comprising a sleeve adapted to receive the ends ofthe pipes, cirf cular wed ges surrounding the pipes within the sleeve, agasket between the wedges, a second gasket between the outer wedge andthe sleeve, athird gasket between the inner wedge and the pipe, adetachable ring carried by said sleeve and having screw-threadedopenings therein, bolts screwed within said openings, L-shaped membersswiveled on the ends of said bolts,and adapted to enter the spacebetween the pipes and the sleeve to engage the outer wedge, and forcethe same inward.

In testimony whereofI have hereunto set my hand in the presence of twosubscribing witnesses.
